Description

  The present invention relates to a recording / reproducing apparatus, and more particularly to a recording / reproducing apparatus including a plurality of disk devices in one casing.

  A recent recording / reproducing apparatus is generally a DVD apparatus using a DVD (Digital Versatile Disk) as a storage medium for large-capacity data in order to meet the demands of the multimedia era.

  The DVD device uses a red semiconductor laser having a wavelength of 650 nm band as an optical disk pickup, and generally has a storage capacity of 4.7 GB.

  On the other hand, Blu-ray Disc (registered trademark) and HD DVD (High Definition DVD) have been announced as optical discs having an increased recording capacity compared to conventional DVDs. Hereinafter, the Blu-ray disc is referred to as “BD”. In the case of BD, three types of recording capacity of single-sided single layer are standardized: 23.3 gigabytes (GB), 25 GB, and 27 GB. In the case of HD DVD, the recording capacity of single-sided single layer is 15 GB. The specification of 20 GB is also being studied. In BD, a digital high-definition broadcast program that lasts for two hours or more can be recorded on one disc. Recording apparatuses using these optical disks are configured to use blue semiconductor laser light with a wavelength of 400 nm for recording and reproducing information.

  As recording / reproducing apparatuses, DVD apparatuses have become quite popular, and a considerable number are used as recording / reproducing media. On the other hand, since the use of media is limited because BD and HD DVD are in the process of spreading, the BD (or HD DVD) disk device and the DVD disk device are provided in one housing. Some devices have been commercialized.

  In these recording / reproducing apparatuses, each disk device is provided with a dedicated tray. Therefore, the user has to select which disk device to use depending on the disk to be used.

In a disc player capable of playing a desired disc while exchanging a plurality of discs, if a disc different from the regular size is placed on the tray, the disc is automatically ejected. This is described in the following patent documents.
Japanese Patent No. 3301834

  However, since the user selects which disk device to use depending on the disk to be used as described above, if a disk is inserted into a different disk device, it is ejected as a non-reproducible disk.

  For this reason, since the other disk device side tray is ejected and the disk is reinserted to perform operations such as recording and reproduction, it is difficult to use.

  An object of the present invention is to improve the operability of a recording / reproducing apparatus including a plurality of disk devices, and more specifically, to improve the operability of disk insertion.

  In order to achieve the above object, the disc device has a plurality of disc devices, each disc device having a disc insertion / ejection tray, and disc discriminating means for discriminating the inserted disc, When the disc inserted in the disc device is determined to be a disc that cannot be reproduced, and when it is discriminated that the disc device other than the disc device is not in operation, the disc tray of the disc device And a means for controlling the discharge of the trays of the disk devices other than the above discretionary.

  The recording / reproducing apparatus switches the operation system for the disk device from the arbitrary disk device to the other disk device in accordance with the ejection of the tray of the arbitrary disk device and the tray of the disk device other than the arbitrary disk device. It is set as the structure provided with the control means.

  In addition, the recording / reproducing apparatus includes display means for notifying that the disk is inserted into the disk apparatus other than the arbitrary as the tray of the arbitrary disk apparatus and the tray of the disk apparatus other than the arbitrary disk are ejected. The configuration.

  Further, the recording / reproducing apparatus includes a display means for informing that the operation system of the disk device is switched in accordance with the ejection of the tray of the arbitrary disk device and the tray of the disk device other than the arbitrary disk device.

  Further, the display means includes a display means that also serves as a display means for notifying that the disk is inserted into a disk device other than the arbitrary disk device.

  And a disc discriminating unit for discriminating the inserted disc, and an operating state of the disc device in a recording / reproducing apparatus each having a disc insertion / ejection tray. Checking means, and a selective discharge control means for selectively discharging the tray of an arbitrary disk device, or the tray and the tray of the disk device other than the arbitrary, according to the results of the disk determination means and the operation checking means. The configuration is as follows.

  According to the recording / reproducing apparatus of the present invention, if it is determined that the disk cannot be reproduced when the disk is inserted, the trays of the other disk devices are also ejected. Become.

  In addition, since the operation system for operating each disk device with the main body or buttons on the remote controller is switched as the tray is ejected, the convenience of the user is improved in terms of operation.

  FIG. 1 shows a recording / reproducing apparatus according to an embodiment of the present invention. The recording / reproducing apparatus of this embodiment is compatible with two types of recording media. Specifically, the BD 51 and the DVD optical disk 52 can be used.

  Note that DVD-type optical disks include DVD-RW, DVD + RW, DVD-R, DVD + R, DVD-RAM, DVD video, music CD, CD-R, CD-RW, and video CD. Collectively, hereinafter referred to as “DVD” 52.

  The front of the recording / reproducing apparatus is provided with receiving portions for BD 51 and DVD 52, and tray open / close buttons 8a and 8b are provided at the center of the openings 2a and 2b. Further, a BD switching button 8c for switching to the BD-side processing and a DVD switching button 8d for switching to the DVD-side processing are arranged below the tray opening / closing buttons 8a and 8b. The switching buttons 8c and 8d are As a disk device selection display, a BD display unit (LED) 91 and a DVD display unit (LED) 92 are provided. In addition, an operation button 8e for recording / playback and the like is disposed in the periphery. A remote control light receiving unit 7 disposed on the front side is for receiving an operation signal from a remote control transmitter (not shown).

  Here, a state in which the BD side tray 11 and the DVD side tray 12 are pulled out is shown. Normally, the BD-side tray 11 and the DVD-side tray 12 are stored inside the casing, and the BD-side tray 11 is ejected outward from the opening 2a by pressing the tray opening / closing button 8a. Yes. When the BD 51 is placed on the tray 11 on the BD side and the tray opening / closing button 8a is pressed again, the tray 11 on the BD side is pulled into the housing. The BD 51 placed on the BD-side tray 11 and inserted into the housing is driven and rotated by the motor unit 14 of the BD-side disc device and is emitted from the BD pickup unit 13. By irradiating with blue semiconductor laser light, the presence / absence detection of BD51, the free space detection of BD51, the data writing to BD51, the data reading from BD51, etc. are performed.

  The tray 12 on the DVD side is normally stored inside the housing in the same manner as the tray 11 on the BD side described above, and is ejected from the opening 2b when the tray open / close button 8b is pressed. When the DVD 52 is loaded on the DVD-side tray 12 and the tray opening / closing button 8b is pressed again, the DVD-side tray 12 is pulled into the housing, and the DVD 52 inserted into the housing is driven and rotated by the motor unit 16 of the DVD-side disk device. At the same time, by irradiating with the red semiconductor laser light emitted from the DVD pickup unit 15, the presence / absence detection of the DVD 52, the free space detection of the DVD 52, the data writing to the DVD 52, the data reading from the DVD 52, etc. are performed.

  As described above, the BD pickup unit 13 uses a blue semiconductor laser beam with a wavelength of 400 nm, and the DVD pickup unit 15 uses a red semiconductor laser beam with a wavelength of 650 nm. In addition, on the disc side, the recording surface of the BD 51 is 0.1 mm from the surface, whereas the recording surface of the DVD 52 is 0.6 mm. Data cannot be written or read. If the data cannot be read from the disk, no data is input to the disk control processing unit 25, so that it is determined that the disk is of a different standard.

  FIG. 2 is a block diagram showing a main internal configuration of the recording / reproducing apparatus. Various broadcast reception signals connected to the interface unit 22, external input signals, IEEE 1394 signals, and the like are switched under the control of the control unit 21, and the content data is converted into data to be recorded by the image / signal processing unit 23. The data is recorded on the BD 51 by the selected disk device 26 on the BD side or on the DVD 52 by the disk device 27 on the DVD side through the disk control processing unit 25.

  Conversely, playback data from the BD 51 of the selected BD-side disk device 26 or the DVD 52 of the DVD-side disk device 27 is input to the image / signal processing unit 23 through the disk control processing unit 25 and displayed on the screen as necessary. The screen display data from the display processing unit 24 is added, converted into a viewing signal, and output from the interface unit 22 to an external output. Then, it can be viewed with a television receiver (not shown) connected to the external output.

  In addition to the control related to the recording / playback process described above, the control unit 21 performs control related to reserved recording, control of the entire apparatus, and the like. The remote control light receiving unit 7, the operation unit 8 (operation system buttons 8a to 8e), BD A display unit (LED) 91, a DVD display unit (LED) 92, a ROM 31, and a RAM 32 are connected. The ROM 31 stores in advance a program for the control unit 21, OSD menu image data, guidance data regarding an operation method based on the disc discrimination result, and the like, and contents (data) processed by the control unit 21 in the RAM 32. Etc. are temporarily stored.

  FIG. 3 is a flowchart showing an operation example of this embodiment. The detailed operation will be described below based on this flowchart.

  When a disc is placed on the BD-side tray 11 and the tray open / close button 8a is pressed, the tray 11 is pulled into the housing, and the disc is driven to rotate by the motor unit 14 of the BD-side disc device, and the BD pickup unit The disk data and the like are read by irradiating with the blue semiconductor laser beam 13 (S1).

  When the data is input to the disk control processing unit 25, the presence / absence of the disk, the type of BD, or the like is determined. If the data is determined to be BD (S2: Yes), the process ends. The process returns to the operation process (S9).

  If the inserted disc is a DVD, the BD pickup unit 13 cannot read data from a DVD that is a disc of a different standard, and no data is input to the disc control processing unit 25. Therefore, the disk control processing unit 25 determines that this disk is not a BD (S2: No).

  If it is determined that the disc is not a BD, the disc cannot be used on the BD side. Therefore, in order to eject the disc, the control unit 21 instructs the disc device 26 on the BD side to eject the tray 11 (S3).

  Next, whether or not the DVD side is in operation such as recording / reproduction or waiting for reservation is confirmed based on the control processing information on the DVD side in the control unit 21, and is in operation such as recording / reproduction or waiting for reservation. If so (S4: Yes), the control on the DVD side is not changed and the operation is continued and the process returns to the normal operation (S9).

  If it is confirmed that the disc is not inserted into the DVD side or is not in an operating state even if it is inserted (S4: No), the control unit 21 instructs the disc device 27 on the DVD side to eject the tray 12. (S5).

  As described above, when the DVD side is in an operation such as recording / reproducing or in a reservation standby state, only the tray 11 on the BD side is ejected in step S3, and no disc is inserted or inserted in the DVD side. However, if it is not in the operating state, the tray 11 on the BD side and the tray 12 on the DVD side are ejected substantially simultaneously in steps S3 and S5.

  That is, according to the result of determining the inserted disc and confirming the operating state of the disc device 27 on the DVD side, only the tray 11 on the BD side is ejected, or the tray 11 on the BD side and the tray 12 on the DVD side are Whether the two trays are discharged is controlled.

  In particular, when the two trays 11 and 12 are ejected, the guidance data stored in the ROM (program) 31 “This disc is not a BD. Please insert it on the DVD side” is displayed on the screen. The video signal is synthesized by the video / audio signal processing unit 23 through the unit 24 and displayed on the screen of a display device such as a television receiver (not shown) connected to the external output of the interface unit 22 (S6). Inform the tray 12 that a disc is to be loaded.

  In the disk device selection display, the BD display unit (LED) 91 remains lit because the BD side is in the selected state. In addition to this, the DVD display unit (LED) 92 blinks. This is done (S7) to inform the player that the disc is to be placed on the tray 12 on the DVD side. The blinking of the DVD display unit (LED) 92 is useful because it can notify that the disc is loaded on the tray 12 on the DVD side even when the display device is not connected to the outside and the screen display cannot be confirmed as described above.

  Further, when the operation system for operating with the operation unit 8 of the main body of the recording / reproducing apparatus or the buttons on the remote controller (not shown) is used by switching between the BD side and the DVD side, the configuration is simplified. However, in the present embodiment, when the above operation is performed even when the operation system is on the BD side, the control unit 21 automatically switches the operation system from the BD side to the DVD side (S8). Therefore, after the disc ejected from the BD side is placed on the DVD side tray 12 and inserted, the user can use the recording and playback buttons on the main unit and the remote control to record and playback on the DVD side without being aware of switching of the operation system. Etc. can be operated.

  Here, the procedure of switching the operation system from the BD side to the DVD side (S8) may be performed after the control unit 21 gives an instruction to eject the tray 12 on the DVD side (S5). This case will be described based on a flowchart showing another operation example of FIG.

  The same processes as those in FIG. 3 are given the same step numbers, and the operations are the same up to step S5. As apparent from FIG. 3, after step S5, even when the operation system is on the BD side, the control system 21 automatically switches the operation system from the BD side to the DVD side (S8).

  Next, the guidance data stored in the ROM (program) 31 “The operation has been switched to the DVD side. Please insert it on the DVD side” through the screen display processing unit 24 and the video / audio signal processing unit. 23 is synthesized with the video signal and displayed on the screen of a display device such as a television receiver (not shown) connected to the external output of the interface unit 22 (S6). With such a display, the operation system for operating the disk device with the buttons on the main unit and the remote control is switched to the DVD side, and the DVD side is operated after the disk is loaded on the tray 12 on the DVD side. I can let you know.

  Further, in the disk device selection display, the BD display portion (LED) 91 remains lit because the BD side is selected, but the DVD display portion (LED) 92 is flashed for a predetermined time. (S7) After that, since the BD display unit (LED) 91 is turned off and the DVD display unit (LED) 92 is turned on, even if there is no external display device connection and the screen display cannot be confirmed as described above, It is possible to inform the user that the disc is placed on the tray 12 and the DVD side is operated thereafter.

  In any case, the procedure of switching the operation system from the BD side to the DVD side (S8) has been described as being performed after the tray 12 on the DVD side is ejected. It may be performed after the disc control processor 25 determines that the disc is a DVD.

  The case where the DVD 52 is inserted into the BD-side disk device 26 has been described above. However, the case where the BD 51 is inserted into the DVD-side disk device 27 can be handled by switching between the BD and the DVD, and the operation on the flowchart is the same. It is.

  As another embodiment, as shown in FIG. 5, a recording / reproducing apparatus in which a BD disk device 26 and a DVD disk device 27 are vertically arranged may be used. Components having the same functions as those in FIG. 1 are denoted by the same reference numerals. In the present embodiment, the BD-side disk device 26 and the DVD-side disk device 27 are placed at positions where a space for taking out / mounting the disk is secured even if the BD-side tray 11 and the DVD-side tray 12 are simultaneously ejected. Even if it is a vertical type, it is possible to carry out the present invention, and there is no difference in the operation on the block diagram and the flowchart.

  In this embodiment, the BD and the DVD have been described as the disk devices, but other HD DVDs and DVDs or BDs and HD DVDs may be used. Further, although two disk devices are used, a plurality of disk devices such as three disk devices (for example, BD, HD DVD, and DVD) may be used.

It is a perspective view which shows the state which pulled out two trays of the recording / reproducing apparatus which concerns on embodiment of this invention outward. It is a block diagram which shows the main internal structures of a recording / reproducing apparatus. It is a flowchart showing an operation example. It is a flowchart showing the other operation example. It is a recording / reproducing apparatus of other example embodiments, and is a perspective view of the state which pulled out two trays outward.
